Pumps, Compressors, Valves
Purpose: With the advent of high quality resin 3D printing, I always thought it would be kind of neat to create a mold and sand cast a part. Fun fact but a lot of components in turbochargers are sand casted; most notably the compressor cover, turbine, and bearing housings. I model the parts below and obtain a CFD solution (no design parameters):
Volute:
Compressor wheel:
Assembly [Compressor stage]:
Using water as a working fluid. Noticed something was off with the pressure outlet within ~5 minutes. Let it finish running.
Chose the wrong direction for my rotating region. I changed the direction and reran it.
Looks way better. Pressure outlet is starting to make more sense.
Nice to see the cut plot show where the velocity is at a maximum, the pressure is at a minimum. This is verifiable by Bernoulli’s equation whereby pressure is inversely related to velocity.
